Reference: AQA
Energy, not matter, moves from the source to the absorber, and when the wave is absorbed the energy is transferred to another store.
The energy moved by a device; a higher-power device transfers more energy in the same time than a lower-power device.
Describing a transfer means naming both ends of it, building the answer as one sentence with two stores in it.
Energy is transferred from the kinetic store of whatever turns the coil, rather than created.
